Could we make this use the same picolibcpp.specs file and just replace -lstdc++ with -lstdc++-noexcept? Do we need different header paths or something?

I was thinking about doing something similar to Newlib nano, but it would probably be easier to keep the same specs file for all configurations.

I made a change in Zephyr to link proper variant: zephyrproject-rtos/zephyr/pull/85945
Is this what you had in mind?
